On completion of the houses, the sheds and their occupants, with all their
bedding and clothing, were treated in the same way, and although this camp,
at the end of the operation, seemed as if it had been drenched by a shower of
rain, by evening everything was as dry as before the washing. The disinfection
of this quarter was completed between March 29th and April 4th, and the
people were allowed to reoccupy their houses on April 11th.
23. A reinforcement of 200 labourers from Bombay arrived on April 4th,
and with their help other quarters of the town were rapidly taken in hand and
subjected to the same treatment, with fire engines aiding the hand pumps ;
but as the first experiment was still under trial, the precaution was taken to
follow up the disinfection with lime-washing. After the Mahomedans of the
Nana Taivd had occupied their houses for a week without any recurrence of
disease, and the experiment had thus proved successful, all lime-washing was
stopped, and no further treatment of houses was adopted beyond disinfection
with corrosive sublimate.
24. At a later stage, when it was possible to undertake the disinfection of
streets and quarters before they became completely infected, it was not found
necessary to disturb the occupants except during the operation of disinfection
and for the few hours during which the houses were drying.
25. The following statistics will give some idea of the results obtained :-
